Metadehumanization in severe alcohol-use disorders: Links with fundamental needs and clinical outcomes.

BACKGROUND: Dehumanization, i.e., the denial of one's humanity, has important consequences for social interactions. Earlier works mainly studied the dehumanizer's perspective, neglecting victims and particularly psychiatric populations. This study's goal is thus to investigate if patients with severe alcohol-use disorders (SAUD) feel dehumanized by others and to reveal factors linked to metadehumanization. METHODS: A cross-sectional study in 120 patients with SAUD as diagnosed by their psychiatrist using DSM-IV criteria. RESULTS: Participants reported significant levels of metadehumanization, which were directly or indirectly linked to fundamental needs threat (γ = 0.41, p < .001), decreased positive emotions (indirect effect = -0.11, p < .05), reduced self-esteem (indirect effect = -0.16, p < .01), reduced use of functional coping strategies focused on the search of social support (γ = -0.20, p < .05), and increased use of dysfunctional coping strategies (indirect effect = 0.15, p < .01) such as excessive alcohol use (indirect effect = 0.10, p < .05). CONCLUSIONS: Patients feel dehumanized by others, an experience linked to important deleterious consequences for patients' wellbeing and treatment.

High slow-wave sleep and low-light sleep: chronic fatigue syndrome is not likely to be a primary sleep disorder.

The status of chronic fatigue syndrome (CFS) is still under debate. Mainstream views still often consider it as an undetected primary sleep disorder or as the psychosomatic expression of a related anxiety or depression syndrome. Both primary sleep disorder and CFS are often related to unrefreshing sleep and affective daytime symptoms. The present study compares nonrapid eye movement sleep distribution between patients with a primary sleep disorder and "pure" CFS patients without sleep or mood disorders. Intensity measures of affective symptoms are also analyzed. Sleep variables of 32 pure CFS (mean age, 41.9 +/- 8.7 years; 25 women), 30 Sleep Apnea Hypopnea Syndrome patients (mean age, 43.7 +/- 6.7 years; 13 women), and 14 healthy controls (mean age, 40.2 +/- 7.6 years; 9 women) were compared. Related affective symptoms were assessed using the self-reported Zung anxiety and depression scales. The study confirms previous reports on increased slow-wave sleep in CFS patients. Both patient groups showed similar sleep duration and efficiency. Sleep efficiency was lower in both patient groups compared with controls. CFS patients showed a higher microarousal index than controls. Anxiety, but not depression symptoms were more intense in the CFS group. The distribution of nonrapid eye movement sleep in CFS differs sizeably from what can be observed in a primary sleep disorder.
